Couldn't load pickup availability
The Power Tank Monster Valve Primary (MV-P) is a 5-pack of 7018 aluminum high-flow valve stems designed to replace standard valve stems in most wheels without any wheel modification, fitting directly into a standard valve stem hole via a 30-degree angle bracket. Each valve weighs 1.1 oz and is 5 times stiffer than a standard metal valve, enabling rapid tire deflation and inflation when paired with a compatible Power Tank CO2 system. This kit is available as a standalone 5-pack or bundled with your choice of Ventoso RED Tire Inflator Gauge in five pressure and display configurations.
Faster Than Any Other Valve Stem
The Monster Valve Primary's high-flow aluminum body moves air at a rate no standard Schrader valve can match. A single Monster Valve Primary delivers a flow rate comparable to four Schrader valves, which means airing down a 40x13.5x17-inch tire from 35 psi to 10 psi takes under 30 seconds. When connected to a Power Tank CO2 system via the included Monster Chuck, that same tire inflates in 40 seconds. For overlanders who air down and back up at every trailhead, that speed compounds across a full set of four tires and eliminates the back-pressure risk that can accompany high-output dual compressors.
Standard Hole, No Drilling Required
The Monster Valve Primary mounts in a standard valve stem hole using a 30-degree bracket, a nut, washer, and rubber grommet. No drilling, no tapping, and no wheel modification is required. An optional spacer accommodates recessed valve stem holes. Because it replaces the stock valve stem entirely, the included TPMS bracket lets you reuse factory or compatible aftermarket TPMS sensors without adding a secondary stem. At 1.1 oz per valve, the Monster Valve Primary does not require tire rebalancing after installation.
Modular Gauge Compatibility Built In
The included Monster Chuck (45-degree elbow) connects directly to any Power Tank Tire Inflator Gauge equipped with a RED Quick-Switch Coupler, including previous-generation Switch-Hitter and Big Kahuna models upgraded with the RED coupler. Buyers who select a bundled variant receive a Ventoso RED Tire Inflator Gauge alongside the 5-pack; the Ventoso RED line is modular, so the gauge head, hose, and coupler can be reconfigured as needs change. The Monster Chuck is exclusive to the RED Quick-Switch Coupler system and does not work with non-RED Power Tank gauges or third-party inflators.
Features
- 7018 aluminum construction: body, collar, and cap are all aluminum for corrosion resistance and rigidity
- 1.1 oz per valve: lightweight enough that tire rebalancing is not required after installation
- 30-degree angle bracket mount: fits most standard valve stem holes without wheel modification; optional spacer for recessed holes
- TPMS bracket included: retains factory or compatible aftermarket TPMS sensors when running the Monster Valve as the sole stem
- Monster Chuck (45-degree elbow) included: connects to Power Tank Tire Inflator Gauges with RED Quick-Switch Coupler for direct inflation
- Lifetime warranty: all components are rebuildable; warranty is void if used with balancing beads

Who This Is For and Isn't
The Monster Valve Primary 5-pack suits overlanders, off-road drivers, and trail enthusiasts who air down and reinflate a full set of tires regularly and want the fastest possible flow rate from a single valve stem per wheel. It is a strong fit for vehicles running standard valve stem holes and for owners who already have or plan to add a Power Tank CO2 system with a RED Quick-Switch Coupler gauge.
The Monster Valve Primary does not fit all wheels. Recessed valve stem holes, bead lock rings, faux lock rings, and certain wheel geometries can prevent installation, and fitment with any specific wheel model is not guaranteed. The Monster Chuck included in this kit does not work with non-RED Power Tank gauges or third-party inflators. The warranty is void if the valves are used with balancing beads. Owners of Japanese vehicles should verify TPMS compatibility before purchasing, as some Japanese TPMS sensors are not compatible with the included TPMS bracket.
Common Questions
Will the Monster Valve Primary fit my wheels?
The Monster Valve Primary is designed for standard valve stem holes and uses a 30-degree angle bracket, nut, washer, and rubber grommet for mounting. An optional spacer handles recessed holes. Fitment is not guaranteed for every wheel: bead lock rings, faux lock rings, recessed holes, and certain wheel geometries can cause interference. Power Tank offers a Monster Valve Fit Kit to test compatibility across multiple MV styles before committing to a full 5-pack purchase.
Are Monster Valve Primaries compatible with TPMS sensors?
Each Monster Valve Primary includes a TPMS bracket that allows you to reuse factory or compatible aftermarket TPMS sensors when the Monster Valve is installed as the sole valve stem. Some Japanese vehicles have TPMS sensors that are not compatible with the included bracket; in those cases an aftermarket TPMS sensor may be required. If you retain the stock Schrader stem as a secondary stem, the TPMS sensor stays on that stem and the bracket is not needed.
What does the included Monster Chuck work with?
The Monster Chuck included in this Monster Valve Primary kit connects to Power Tank Tire Inflator Gauges equipped with a RED Quick-Switch Coupler. This includes current Ventoso RED gauges and previous-generation Switch-Hitter and Big Kahuna models that have been upgraded with the RED Upgrade Kit. The Monster Chuck does not work with non-RED Power Tank gauges or with third-party tire inflators.
What is included in the Monster Valve Primary 5-pack kit?
The Monster Valve Primary 5-pack includes five MV-P valves (each with a TPMS bracket), a Monster Chuck with 45-degree elbow, a dual Schrader and Monster Core tool, blue thread sealant, silicone grease for maintenance, and a zipper bag. Buyers who select a bundled variant also receive a Ventoso RED Tire Inflator Gauge; the standalone 5-pack variant does not include a gauge.
Does the lifetime warranty cover all uses?
Monster Valve Primaries carry a lifetime warranty and all components are rebuildable. The warranty is void if the valves are used with balancing beads. Power Tank states that even out-of-warranty valves can be serviced and rebuilt, and the company can be contacted directly for troubleshooting support.
